Source: Red Sox show interest in reliever Matt Guerrier

According to a major league source, the Red Sox have shown interest in free agent relief pitcher Matt Guerrier. The right-hander, who has spent his entire seven-season major league career with the Twins, went 5-7 with a 3.17 ERA in 74 games with Minnesota in 2010. In the previous two seasons he led the American League in appearances with 76 and 79, respectively.

The 32-year-old had been classified as a ‘Type A’ free agent, but the Twins failed to offer him arbitration thereby not costing any team that would sign the righty a draft pick. Primarily a ground-ball pitcher, Guerrier’s best pitch is a slider, which helped limit right-handed batters to a .210 batting average in ’10. He also walked just 22 in 71 innings last season.
